As shown in FIGS. 4 (a) and 4 (b), the stepped portion 53 has an inclined surface 53a formed so as to rise toward the rear of the vehicle at the middle portion in the vehicle longitudinal direction. The step portion 53 has flat surfaces 53b and 53c extending horizontally from the front end and the rear end of the inclined surface 53a to the front side and the rear side, respectively. As a result, the step 53 has a constant height difference from the upper end surface 38. The flat surface 53c is connected to the lower end surfaces of the lid wall portions 41b and 42b (see FIG. 6) of the respective guide grooves 41 and 42 on the rear side without causing any step. The rear end of the lid wall 51 is disposed at a position in the front-rear direction in the vicinity of the boundary between the inclined surface 53a and the flat surface 53c, and the rear thereof is opened in the height direction. This is to avoid interference with the second function bracket 24.

  Similarly, as shown in FIGS. 4 (a) and 4 (b), the side wall 54 (lower end surface) has an inclined surface 54a formed so as to rise toward the rear of the vehicle at an intermediate portion in the vehicle longitudinal direction. The flat surfaces 54b and 54c extend horizontally from the front end and the rear end of the inclined surface 54a to the front side and the rear side, respectively. Thus, the side wall 54 is placed on the upper end surface 38 without interfering with the upper end surface 38. The side wall 54 is in contact with the upper end surface 38 (planes 38b and 38c) at the planes 54b and 54c.

  With such a configuration, the upper end surface 38 and the inner wall surface of the block 50 (the stepped portion 53, the side wall 54) are a pair of guides having a U-shaped cross section in which the opening sides of the upper end surface 38 and the block 50 (the stepped portion 53 and the side wall 54) face each other. Grooves 55 and 56 are formed (see FIG. 6). That is, the guide grooves 55 and 56 are configured by two parts of the front housing 30 and the block 50 that are divided in the height direction, and particularly the front portion has a closed cross-sectional shape due to the lid wall 51. As shown in FIGS. 4 (a) and 4 (b), each guide groove 55, 56 rises toward the rear of the vehicle in the vehicle front-rear direction intermediate portion, and its cross-sectional shape is a cross-section of the guide grooves 41, 42. It matches the shape (see FIGS. 5 and 6). The rear ends of the guide grooves 55 and 56 are continuously connected to the front ends of the guide grooves 41 and 42.

  As shown in FIG. 5, a pair of columnar guide portions 24 a and 24 b protrude from the front end portion of the second functional bracket 24 on both sides in the width direction. The guide portions 24 a and 24 b The guide grooves 55 and 56 are mounted so as to be positioned in the width direction and the height direction. Accordingly, the guide portions 24a and 24b are guided by the guide grooves 55 and 56 as the second functional bracket 24 moves backward, and are guided to the guide rails 22 (guide grooves 41 and 42).

  As shown in FIGS. 2 and 6, the block 50 includes flange-like mounting pieces 57 and 58 disposed above the support walls 43 and 45, respectively. The block 50 and the front housing 30 are coupled to the nuts 44 and 46 by screwing bolts 59 and 60 passing through the guide rail 22 sandwiched between the support walls 43 and 45 and the mounting pieces 57 and 58. ing. That is, the block 50 and the front housing 30 are fastened together with the guide rail 22.

  As shown in FIGS. 2 and 7, each side wall 54 is formed with a fitting protrusion 61 that protrudes in the front-rear direction so as to face the fitting groove 40a. The block 50 is positioned in the width direction by the fitting protrusions 61 being fitted into the fitting grooves 40a, and the upward movement is restricted. Accordingly, the block 50 is secured to the front housing 30 by being prevented from coming off in the height direction with respect to the front housing 30.

By exhibiting a U-shaped cross-sectional shape, the rigidity can be increased, and both guide portions 24a, 24b of the second functional bracket 24 are positioned more firmly in the height direction, and the guide portions 24a, 24b are moved up and down. It can be guided to the guide rail 22. Further, since the shape in the width direction of the pair of guide grooves 55 and 56 is defined by only one component (the block 50 having the pair of side walls 54), dimensional accuracy (pitch accuracy) in that direction can be easily secured. Can do. And it suppresses that an unnecessary level | step difference arises between a pair of guide grooves 55 and 56 and the guide rail 22 (guide grooves 41 and 42), and both guide part 24a, 24b of the 2nd function bracket 24 is made into the guide rail 22. It can guide more smoothly.

  Furthermore, since both the block 50 and the front end portion of the front housing 30 opposed to the block 50 have a U-shaped cross-sectional shape, in each molding process, the pair of molds is basically simply moved relative to the opening direction. It's okay. Accordingly, the slide mold that is moved in the crossing direction, which is necessary for forming the guide groove in the conventional molding process, is not necessary, and the mold can be easily manufactured and the cost can be reduced. Further, since the mold does not have a nested structure, an operator dedicated to the molding machine is not required.

  (2) In the present embodiment, an increase in the number of parts can be suppressed by using the existing front housing 30 that connects the guide rails 22 on both sides for forming the pair of guide grooves 55 and 56.

  (3) In the present embodiment, the block 50 and the front housing 30 are fixed with the guide rail 22 interposed therebetween. Accordingly, since the block 50 is fixed together with the guide rail 22 and the front housing 30, the block 50 can be fixed using, for example, the existing fixing portion (fastening portion) of the guide rail 22 and the front housing 30.

  (4) In the present embodiment, upward movement of the block 50 is restricted by fitting both the fitting protrusions 61 with the fitting groove 40a. Accordingly, it is possible to prevent the block 50 from coming off from the front housing 30 in the height direction. In addition, the number of parts to be fixed by fastening the block 50 and the front housing 30 can be reduced, and the number of parts can be reduced to the extent that fasteners (bolts, nuts, etc.) are unnecessary. That is, the block 50 only uses the existing fixing portion (fastening portion) of the guide rail 22 and the front housing 30, and does not need to add any other parts for fixing.

  (5) In the present embodiment, the nuts 44 and 46 are embedded in the housing recesses 43b and 45b that are recessed in the height direction in the front housing 30 (support walls 43 and 45), so that the block 50 and the front housing 30 are provided. It can suppress that an unnecessary protrusion part arises in the fixed part. Further, if the nuts 44 and 46 are prevented from being rotated by the housing recesses 43b and 45b, the fastening operation using the bolts 59 and 60 can be performed smoothly.

  (6) In this embodiment, by providing the front housing 30 with the cable guide 47 for guiding the drive cable 32, the number of parts can be reduced, and as a result, the cost can be reduced.

  (7) For example, compared with a structure in which the functional bracket is positioned in the width direction with the function bracket sandwiched between separate blocks arranged on both sides in the width direction, the generation of rattle is improved by improving the dimensional accuracy in the width direction. It can be suppressed and the number of parts can be reduced. Further, a fastening member for integrating the blocks on both sides, which is necessary when such a structure is adopted, is also unnecessary.

  (8) For example, in the case of a structure in which the functional bracket is positioned in the height direction with a movable part, a gap for allowing the movement of the movable part is necessary, and this may be a cause of occurrence. Factors can be eliminated.

In addition, you may change the said embodiment as follows.
-In the said embodiment, the arrangement | positioning relationship of the nuts 44 and 46 and the volt | bolts 59 and 60 in the height direction may be reversed, and the heads of the volt | bolts 59 and 60 may be embedded in the accommodation recessed parts 43b and 45b. In this case, it is preferable to prevent the heads of the bolts 59 and 60 from rotating with the housing recesses 43b and 45b.

In the embodiment, the block 50 and the front housing 30 with the guide rail 22 interposed therebetween may be fastened with caulking pins or the like.
In the above-described embodiment, the front end portions of the block 50 and the front housing 30 may be fixed with an appropriate fastener or the like instead of the fitting of the fitting groove 40a and the fitting protrusion 61.

In the above-described embodiment, a dedicated component different from the front housing 30 may be adopted for forming the pair of guide grooves 55 and 56.
In the embodiment, a pair of side walls (side walls 54) that form the pair of guide grooves 55 and 56 may be provided in the front housing 30.
